Smart watch Xiaomi: which one to choose?

The wearable electronics market reached an incredible level of maturity in 2026, and Chinese giant Xiaomi, along with the ecosystem brands, offers such a wide range of gadgets that it is easy for an unsophisticated user to get confused. Choosing the right device is no longer a matter of mere availability of free tools, becoming a difficult task to match the functionality for specific life scenarios. Some models are sharpened for professional sports, others for autonomy, and others serve as a stylish accessory with advanced notification functionality.

In this article, we will discuss in detail which Xiaomi smart watches will best suit you, based on current characteristics, sensor quality and software support. We will not just list the characteristics, but try to understand what lies behind marketing names and how this affects the real experience of use in everyday life.

Before you go to specific models, it's important to decide on priorities: Are you willing to charge your device every 24 hours for premium materials and a bright screen, or is it more important for you to forget about charging for two to three weeks?

Key criteria for choosing a smart watch

The first thing to look at when buying is the operating system and compatibility. Xiaomi devices fall into two large groups: HyperOS (formerly MIUI Watch)-based devices with full app and store installations, and simpler trackers on proprietary OSes with limited functionality. Full-featured smartwatches allow you to install cards, messengers and even answer calls right from the wrist, while fitness bracelets and light versions mostly display notifications.

The second critical parameter is autonomy, and there's a trade-off: the smarter the watch, the smaller it lives. AMOLED-The screens and Always-On Display require daily or bi-day charging, while models with E-Ink screens or simplified electronics can last up to a month.

The quality of the straps is also important, as Xiaomi’s mounting standards change frequently. If you plan to wear the watch all the time, including sleep tracking, the strap material (fluoro rubber, leather, fabric or metal) will play a crucial role in comfort. Cheap silicone straps can irritate the skin when worn for long periods.

⚠️ Note: When buying a Xiaomi watch for iOS (iPhone), be sure to check the list of supported features.Some advanced features, such as replying to messages or installing third-party dials, may be stripped or unavailable on Apple devices.

Mi Band: King of the Budget Segment

The Mi Smart Band (formerly known as the Mi Band) remains the most popular entry-point in the world of wearable electronics, with 9th and 10th generation models still relevant in 2026. NFC-payment modules and large displays occupying almost the entire area of the front panel.

The main advantage of the series is its incredible autonomy: with moderate use (disabling constant monitoring of the pulse and reducing brightness), they live a calm life of 14-20 days, which makes them ideal companions for business trips and hikes, where there is no possibility to charge gadgets often.

However, when you choose the Mi Band, you sacrifice the premium of materials. Plastic body and the lack of a physical button (in some models, the control is completely touch-sensitive) can be uncomfortable in the gym when your fingers are sweating. In addition, the screens here, although bright, are inferior in pixel density to flagship models.

• 🏃‍♂️ Ideal for: Beginner athletes and those who need a simple sleep and foot tracker.
• 💰 Price/Quality: Best ratio on the market, replacing straps costs a penny.
• 🔋 Charging: Built-in USB-connector (in the latest models) allows charging without cable, but requires caution when installed in the docking station.

Xiaomi Watch S: Style and Technology

If the Mi Band is a utilitarian tool, the Xiaomi Watch S series (including the S3, S4 and their Pro/Sport variants) is a statement piece. It uses premium materials like stainless steel, sapphire glass and titanium, and it's not just designed to show time, but to complement business or everyday look.

Inside these buildings, there's a powerful piece of iron. GPS-The module delivers track accuracy comparable to a professional Garmin sports watch.The operating system allows you to install apps, download music and even make calls through a built-in speaker and microphone if you have a smartphone connected or there is eSIM support.

💡

For maximum battery life on the Watch S, use Power Saving mode at night and turn off Always-On Display if there is no urgent need.

An important feature of the S series is modularity: Some models allow rapid change of not only the strap, but also the outer rim (bezels), transforming the look of the watch in seconds, a unique feature that is rarely seen by competitors in this price segment.

Amazfit Ecosystem: When Xiaomi is Small

You can't talk about Xiaomi watches without mentioning the Amazfit brand. It's technically a separate company (Huami), but historically and technologically they're closely related to Xiaomi. Many Amazfit models (GTR, GTS, T-Rex series) use the same sensors and algorithms as Xiaomi watches, but often offer more advanced software and unique features.

The T-Rex series deserves special attention for extreme sports enthusiasts. This watch has a military standard of strength (MIL-STD-810G), withstands extreme temperatures, impacts and submersions. If you plan to dive, mountaineering or work in harsh conditions, a regular Xiaomi Watch may not be suitable, and the T-Rex Ultra will cope with the task.

The Zepp OS software that runs Amazfit is often considered more stable and rich in health analysis features than standard Xiaomi software, and it implements complex metrics such as fitness readiness (PAI), detailed sleep breathing analysis and stress.

However, the integration with the Xiaomi Home ecosystem from Amazfit may be less profound.If you are actively using Xiaomi’s smart home, your home watch may be more convenient for quickly controlling scenarios right from the wrist.

⚠️ Note: When buying Amazfit and Xiaomi Watch, pay attention to the region version (Global, CN, EU). Chinese versions may have problems connecting to European servers, lack of Russian language in the system or incorrect notifications from WhatsApp and Telegram.

Sports and Health: What Sensors Can Do

Xiaomi’s modern smartwatch is not just pedometers; in 2026, it will feature 6th and 7th generation optical pulse sensors that can track blood oxygen saturation (SpO2), heart rate variability (HRV), and even ECGs (depending on model and region).

GPS accuracy is critical for runners and cyclists. Xiaomi’s flagship models use dual-band navigation, allowing tracks to be built even in dense urban areas or dense forests with minimal errors. Budget models can walk 10-20 meters on a map, which is unacceptable for a professional.

The Xiaomi algorithms have learned to recognize the phases of REM and deep sleep, as well as daytime nap. However, it is worth remembering that no smart watch is a medical device. Health data is informative and should not be used to make diagnoses.

• 🏊‍♀️ Waterproof: Most models are labeled 5 ATM, It allows you to swim in the pool, but not to scuba dive.
• 🧘‍♂️ Training modes: Supports more than 150 activities, from yoga to crossfit, with automatic start recognition.
• 🩸 Monitoring: Round-the-clock pulse, oxygen levels and female cycles are the standard for all current models.
